LOCOMOTIVE-BELL.

Specification of Letters Patent. f Patell-(NIYNOV, 11,119.13,

Appli-cation led June 30, 1913. 'Serial No. 776,491. i i

`height is available for their installation on.

the top of the boiler, whereby the y total height of the bell-and its accessories may be substantially reduced without aecting the tone of the bell or impairing its efficiency as an alarm. 1

The improvement claimed is hereinafter fully set forth.

is a view, partly in elevation and partly in section, of a locomotive bell and its accessories,`embodying my invention, taken'in4 -the axial plane of oscillation of the bell;

Fig. 2, a partial similar section, illustratinga structural modification of the means for fastening the bell to its shaft; Fig. 3,4 a

transverse section taken at a right angle to Fig. and, Fig. 4, an end view, in elevatien, of. the bell stand, as seen from the left,

showing the operating crank arm and stop spring.

In the practice of lny invention, I provide a bell. l, which, except as hereinafter described, is of the ordinary form. Two op-` positely -disposer'l perforations, l, are formed .transversely in the bell, through .fwli-'if'cli pcrforations there extends a supporting l shaft, 2, journaled in bearings, 3a, 40 fcrmedon the tops of the`vertically extending members of a bell stand, 3, the base of which is suitably curved to fit on, and be secured to, the top of a locomotive boiler. The shaft, 2, is located in substantially the ordinary nmnnrr, relatively to the center of gravity minor change in its location, as is made being due to the tact that the bell yoke usually applied. is dispensed with.

The hell is interorly connected to the supporting shaft b v an eye bolt, 4, which -is preferably. as shown, bifurcated at its lower end and passes through a central perforation in the top ot' the bell. The forks of the lower end of the eye bolt are perforated to tit truly on the shaft, 2, and the upper end In the accompanying drawings: Figure -1A .iff the oscillating members, such,

of the eye bolt is threaded and engagedlby. a nut, 4a, and the toplof the bell,on which the nut bears, is downwardly recessed, so

that the` nut does not. project toanyfper-l ceptible extent, abovcthe bell. tecesses, 2a, are cut in. the shaft, 2, on opposite sides of the forks of the eye bolt, andare engaged by lugs, 1b, which project downwardly from theV top of the bell, relative movement-,of the bell and supporting shaft ,being thereby prevented. As shown in Fig; 1,1the lugs, 1b, are cast integral with the bell, and as lshown in F igs. 2 'and 3, they 'are made asa single separate piece, which'inay 'be of rcheaper Ina-'- terial than the bell, and which 'is provided with an annular projection, `1c,fittinfg around the eye bolt, 4, and in thetop of the bell, and secured thereto by the'nut, 4t..l

A,clapper, 5, is suspended 0n the supporting shaft, 2, an eye on its ,ripper end fitting in the space between the forksof the eye bolt, and it will be obvious that, if preferred, the upper end of the clapper may be bifurcated, instead vof so dividing the'eye bolt, this being the mechanical equivalent of the construction shown.

A crank arm, 6, having'a pin, 63,011 its.

lower end, for the attachment ofan operating bell rope, Iis fixed on one end of the supporting'shaft, 2, said crank arm having oppositely disposed lateral wings, 6", on its upper end,l which are adapted to abut againstthe upper end of a. plate spring-7, the lower end'of which is secured to a lug, 3b, on one of the vertically extending 1nembers of the bell stand, 3, and which extends upwardly to within a short distance of the hub of the crank arm, 6. By the bearing of one or the other of the wings, 6b, against'the spring, as the bell reaches its maximum determined traverse or swing in either direction, the bell is prevented from overturning, and its swing is restricted to the desired limit.

It will Vbe seen that by the elimination of the usual` bell yoke, the weight. and the height of the structure areboth substantially reduced, the latter reduction being one which is often lvery desirable in large locomotives of recent construction, and also that the construction is of such character that its several members can be inexpensively manufactured and readily assembled in position for use.

I claim as my invention and desire to secure by Letters Pat-cnt:

1. 4The combination of a bell stand, a transversely perforated bell, a supporting shaft journaled in said stand and extendon said snaft, means for oscillating said l shaft, andv'mcaiis for `limiting the degree of oscillation of said shaft.

` 3. The combination of,-a bell stand, a transversely perforated bell, a supporting -shaft journaled in said stand and extend ing through the bell, a bolt having a lower eye fitting* on said shaft and attached at its top to the bell,'a. clappcrf journaled on said shaft, and means for oscillating said shaft. 4;. The combination of a bell stand, a transversely perforated bell having a central recess in its top, aI supporting shaft journaled in i the bell stand and extending through the bell, a bolt having a lower eye fitting on said shaft and extending through the top of the bell, a nut engaging said bolt and bearing on the recess of the bell, a

clapper. journaled on the supporting shaft,

and means for oscillating said shaft.

'5. The combinati n .of a bell stand, a transversely perfor ted bell, a supporting shaft journaled in said stand and extending 'through the bell, a bolt having a lower eye fitting on said shaft and attached at its top to the bell, a lug extending from the top of the bell and engaging a recess in said shaft, a clapper journaled on said shaft, and means for oscillating said shaft.

6. The combination of a bell stand', a

supporting shaft journaled in said stand, a

bell connected to said shaft, a clapper journaled on sald shaft, an operatlng crank arm fixed on-said shaft and having oppositely disposed lateral wings, and a vertical plate spring fixed to the bell stand in position to be contacted with by said Wings at the extremities of the normal range of oscillation of the crank arm.
